the additives can have the absorption ability for light in a wavelength range of 600 nm - 800 nm in the imaging optical system lens assembly so as to reduce extra red light or infrared light, or the additives can have the absorption ability for light in a wavelength range of 350 nm - 450 nm in the imaging optical system lens assembly so as to reduce blue light or ultraviolet light. Therefore, additives can prevent the image from interfering by light in a particular wavelength range.
the additives can be homogeneously mixed with the plastic material, and the lens elements can be made by the injection molding method.
the additives can be coated on the lens surfaces to provide the aforementioned effects.
the imaging optical system lens assembly of the present disclosure when a surface of the lens element is aspheric, it indicates that entire optical effective region of the surface of the lens element or a part thereof is aspheric.

the lens element has positive refractive power or negative refractive power, or the focal length of the lens element, all can be referred to the refractive power, or the focal length, in the paraxial region of the lens element.
a critical point is a non-axial point of the lens surface where its tangent is perpendicular to the optical axis; an inflection point is a point on a lens surface with a curvature changing from positive to negative or from negative to positive.
the image surface thereof based on the corresponding image sensor, can be flat or curved.
the image surface can be a concave curved surface facing towards the object side.
the imaging optical system lens assembly of the present disclosure can selectively include at least one image correcting element (such as a field flattener) inserted between the lens element closest to the image surface and the image surface, thus the effect of correcting image aberrations (such as field curvature) can be achieved.
the optical properties of the aforementioned image correcting element can be adjusted corresponding to the demands of the imaging apparatus.
